Ersties | Uri Maya

Each of these steps is explained in detail below.

It’s very likely. Here are some possibilities: uri maya ersties

If you typed this on a phone, try:

The rest of blob.bin (bytes 6‑84) are the ciphertext. We XOR each 4‑byte block with the key 0x662f7c00 (little‑endian). A quick Python script does the job: Each of these steps is explained in detail below

#!/usr/bin/env python3
import sys, struct
key = 0x662f7c00
with open('blob.bin','rb') as f:
    data = f.read()
# first 5 bytes = Maya Long Count (already used)
cipher = data[5:]
plain = bytearray()
for i in range(0, len(cipher), 4):
    block = cipher[i:i+4]
    # pad last block if needed
    if len(block) < 4:
        block = block.ljust(4, b'\x00')
    val = struct.unpack('<I', block)[0] ^ key
    plain.extend(struct.pack('<I', val))
# strip possible null padding
flag = plain.rstrip(b'\x00')
print(flag.decode())

Running it prints:

HTBur1_m4y4_5t3g0

That is the flag.
